...d but in this window lockres can get reused. This leads to BUG. This patch modifies dlm_run_purgelist to skip lockres if it's in use and purge next lockres. It also sets DLM_LOCK_RES_DROPPING_REF before releasing the lockres spinlock protecting it from getting reused.

This patch is against ocfs2-1.4 and also applies to ocfs2-1.2. ocfs2 mainline requires only the first portion of the patch and hence will make a separate patch for that.

All, Please review the patches backported to 1.4 from mainline. Sunil

This fix modifies o2net layer behavior which seems to trigger some DLM race issues during umount/evictions that needs to be fixed as well. I am working on the dlm issues but meanwhile please review this patch. Thanks, --Srini

Next two patches are backport of orphan scan timer patches to ocfs2-1.4

...t ac->ac_allow_chain_relink = 1; then call ocfs2_search_chain() one time and disable it again, and then we run out of credits. Fix is to allow relink by default and disable it in ocfs2_block_group_alloc_discontig.

...eventually the orphan gets cleaned when the inode is purged. When the timer is fired, the node acquires OCFS2_LOCK_TYPE_ORPHAN_SCAN lock in EX mode and verifies the recent scan time. It skips if any node did a scan within the last timeout. This is to avoid frequent scans.

Hi, I have added heartbeat mode as global, but when I do a mkfs and mount, and then check the mount, it says I am in local mode. Even /sys/kernel/config/cluster/ocfs2/heartbeat/mode says local.
